The influence of ambient temperature is also one of the important factors. The construction of bridge construction machinery should control the pre-bend according to the design requirements.

Erecting machine is a new type of erecting machine equipment. In the bridge crane, it is more versatile, and it is especially suitable for large-tonnage, long-span and double-span concrete box girder.

In the daily use of road bridge machine and other lifting equipment, we can not just use, do not maintain it, this is very dangerous, it is easy to make equipment failure, in the use of faulty equipment, the danger is likely to slowly come!

Process uses erecting machine in what will emerge? Environmental temperature is also an important factor. Pre-camber construction bridge construction machinery should be controlled in accordance with the design requirements.

Bridge girder launcher crane is short for bridge erecting machine. The advantage of gantry type rigid frame is outstanding. Lightweight structure, good wind resistance.

A bridge launching girder crane is a device that places prefabricated beams on a prefabricated pier, this type bridge girder launcher is a special-purpose mobile gantry crane used in bridge construction.

As one of the important lifting equipment for building bridge engineering, bridge-building machine is one of the most frequent movements: the longitudinal movement of bridge girder launcher. When talking about the longitudinal movement of the bridge girder launcher

1. Overload protection device Whether the bridge girder launcher overload protection device is sensitive and reliable, meets the design requirements, the opening pressure of the hydraulic overload protection device; whether the mechanical, electronic and integrated overload protector alarms and cuts

Launcher girder crane is a very helpful bridge building equipment, which can be divided into road, highway and high speed railway building works. To operate the launcher girder crane safely and finish construction task in time, it is vital to pay attention to the safe operation rules of this device.
